Torque - Finding the unknown weight

  • #1

Homework Statement


Torque is used to determine the weight of an object. A 10.0 m long pole weighing 20.0 N has its center of gravity 2.00 m from one end. An object of unknown weight is hung at the end opposite the center of gravity. With the object hanging at this end, the pole now balances 2.00 m from the unknown weight. What is the weight of the unknown weight? Ans:60.0


Homework Equations


T = F * R


The Attempt at a Solution


T = 20 * 2
= 40 ?

Ok lemme have a crack at it.I assume that unknown object is at the other end of stick (not the center of gravity end). So

Tcw = Tccw
2*X = 6*20
X=60 N
